Java is a programming language and computing platform first released by Sun Microsystems in 1995. It is a class-based, object-oriented language that is designed to be portable, meaning that Java code can run on a wide variety of hardware and operating systems. Java is widely used to develop enterprise-level applications, mobile apps, video games, and other types of software.

"We do what we must, because we can"

Whenever you get an idea, you must ask your self some questions: is this possible? How long would it take? Is it worth it? Should I even do this? However, some ideas politely ignore all of these questions and go straight into action.

Introducing the World Slate:

World Slate, The Great Work, Ghost-Circle, "Sophia why the fuck did you even think of making this," whatever you call it; it is a massive Spell Circle that is approximately 11 thousand blocks by 12 thousand blocks large. This covers about 30% of the overworld of the HexxyTest server.

For those who don't know Spell Circle Tech: a Spell Circle calculates ambit based on how big it could be, rather than based on where it does runs. So you can "trick" a Spell Circle into having a massive ambit by having a looping system that connects to outer "prongs" via a directrix. This is how the World Slate has complete ambit over 30% of the whole overworld. However, there is a large problem, lag.

Spell circles (shouldn't) gain lag while running; since they now, in 1.20, run each pattern while going over them. On the other hand, during a start-up a Spell Circle needs to calculate what slate it can run on, caching it into its NBT data. This seems like it could be a large source of lag, since it's doing a flood fill over possibly thousands of blocks; but, that is only half true. If all the slate blocks are in the same loaded area, the flood fill only takes a few milliseconds, barely anything. But, to get the block data to find where the slate could go, it has to load the chunk the slate in, which is not that bad, IF the slate does not go across ~1400 chunks. Loading, and calculating, that many chunks will lag a server badly (maybe even kill it); so the project seems hopeless.

But, there is a way to fix the lag of loading ~1400 chunks in less than a tick, optimizations.

Since I know Java and some bits about modding, I have been trying to fix some more laggy parts of Spell Circles. I have already fixed a moderate lag source of looping Spell Circles (chunk bans are fun!). So it hypothetically shouldn't be too hard to somehow optimize Slate Discovery.

There are 2 large problems with optimizing Slate Discovery though: How to locate them, and how to store the found slate. The 2nd problem is much easier to solve, rather than storing them in a set of raw Vec3s like it does now, it would be best to compress them down (maybe into a string representation or something) then uncompresses them when it is running. This could be done with a small, quick compression algorithm.

However, optimizing the finding of the slate is another problem. The best system would be finding the slate without loading the chunks, but this is impossible, so we need to use a 2nd method.

That 2nd method would be to break up slate discovery over time, so instead of loading ~1400 chunk all at once, we can just load 200 chunks each tick until we get all ~1400 chunks. This system does have some minor problems, and a big problem. The small problems would be: how to keep discovery going if the server closes, how would you serialize the discovery list, how would you tell the impetus to look over time, etc. And these problems are simple enough; however, the big kicker is that the player could move slate during discovery.

As said by Chloe, people could move the slates in discovery, meaning they could cheat the system by moving the slates while they are being scanned, and still get "world ambit" for about fre. This is, unfortunately, just a problem that would have to be accepted for a system like this.

I do think that flaw can be somewhat ignored though. Since, if you are willing to make a Hex (or a massive contraption) that works every tick to move earth-shattering amounts of slate; then you can have world ambit fuck it.

Or you know, instead of doing this whole massive problem if optimizing slate scanning just do something like re-adding the slate limit

However, if you have any ideas of how Slate Discovery could be optimized; or if I am insane for starting this project; please let me know.

Understanding Object-Oriented Programming and OOPs Concepts in Java

Object-oriented programming (OOP) is a paradigm that has revolutionized software development by organizing code around the concept of objects. Java, a widely used programming language, embraces the principles of OOP to provide a robust and flexible platform for developing scalable and maintainable applications. In this article, we will delve into the fundamental concepts of Object-Oriented Programming and explore how they are implemented in Java.

Object-Oriented Programming:

At its core, Object-Oriented Programming is centered on the idea of encapsulating data and behavior into objects. An object is a self-contained unit that represents a real-world entity, combining data and the operations that can be performed on that data. This approach enhances code modularity, and reusability, and makes it easier to understand and maintain.

Four Pillars of Object-Oriented Programming:

Encapsulation: Encapsulation involves bundling data (attributes) and methods (functions) that operate on the data within a single unit, i.e., an object. This encapsulation shields the internal implementation details from the outside world, promoting information hiding and reducing complexity.

Abstraction: Abstraction is the process of simplifying complex systems by modeling classes based on essential properties. In Java, abstraction is achieved through abstract classes and interfaces. Abstract classes define common characteristics for a group of related classes, while interfaces declare a set of methods that must be implemented by the classes that implement the interface.

Inheritance: Inheritance is a mechanism that allows a new class (subclass or derived class) to inherit properties and behaviors of an existing class (superclass or base class). This promotes code reuse and establishes a hierarchy, facilitating the creation of specialized classes while maintaining a common base.

Polymorphism: Polymorphism allows objects of different types to be treated as objects of a common type. This is achieved through method overloading and method overriding. Method overloading involves defining multiple methods with the same name but different parameters within a class, while method overriding allows a subclass to provide a specific implementation of a method that is already defined in its superclass.

Java Implementation of OOP Concepts:

Classes and Objects: In Java, a class is a blueprint for creating objects. It defines the attributes and methods that the objects of the class will have. Objects are instances of classes, and each object has its own set of attributes and methods. Classes in Java encapsulate data and behavior, fostering the principles of encapsulation and abstraction.

Abstraction in Java: Abstraction in Java is achieved through abstract classes and interfaces. Abstract classes can have abstract methods (methods without a body) that must be implemented by their subclasses. Interfaces declare a set of methods that must be implemented by any class that implements the interface, promoting a higher level of abstraction.

Inheritance in Java: Java supports single and multiple inheritances through classes and interfaces. Subclasses in Java can inherit attributes and methods from a superclass using the extends keyword for classes and the implements keyword for interfaces. Inheritance enhances code reuse and allows the creation of specialized classes while maintaining a common base.

Polymorphism in Java: Polymorphism in Java is manifested through method overloading and overriding. Method overloading allows a class to define multiple methods with the same name but different parameters. Method overriding occurs when a subclass provides a specific implementation for a method that is already defined in its superclass. This enables the use of a common interface for different types of objects.

Final Thoughts:

Object-oriented programming and its concepts form the foundation of modern software development. Java, with its robust support for OOP, empowers developers to create scalable, modular, and maintainable applications. Understanding the principles of encapsulation, abstraction, inheritance, and polymorphism is crucial for harnessing the full potential of OOPs concepts in Java. As you continue your journey in software development, a solid grasp of these concepts will be invaluable in designing efficient and effective solutions.
